Following a major earthquake, a 15-metre tsunami disabled the power supply and cooling of three Fukushima Daiichi reactors, causing a nuclear accident beginning on 11 March 2011. All three cores largely melted in the first three days.
What caused the Fukushima earthquake 2011?
The earthquake was caused by the rupture of a stretch of the subduction zone associated with the Japan Trench, which separates the Eurasian Plate from the subducting Pacific Plate.
What happened at Fukushima 10 years ago?
Fukushima Nuclear Accident 10 Years Later : Short Wave In 2011, villages and towns around the Fukushima Daiichi Nuclear plant in Japan were evacuated because of a series of meltdowns caused by a tsunami. Ten years later, some of the villages and towns are slowly reopening.
Why did Fukushima explode?
The hydrogen explosion in reactor 4 was caused by hydrogen coming out from the spent fuel pool. In that pool, there were (and are) used nuclear fuel rods that released and still release decay heat. As the water level dropped, the used fuel rods were exposed to the air and hydrogen was formed.
Was Japan prepared for the 2011 tsunami?
It was widely believed that Japan was one of the most prepared countries in the world for tsunami events. In one sense, the belief was right. The 2004 Sumatra–Andaman earthquake tsunami (Mw 9.0–9.3) killed 220 000 people, while the 2011 event (Mw 9.0) caused over 18 000 fatalities.
Was Japan prepared for the 2011 earthquake?
Because of a long history of frequent, sizable earthquakes, Japan was relatively well-prepared for the latest quake. Japan could not protect its entire coastline against tsunami with its system of seawalls.
How many died at Fukushima?
The Tōhoku earthquake and tsunami killed over 15,000 people from effects unrelated to destruction of the reactors at Fukushima….Fukushima Daiichi nuclear disaster casualties.

Is Fukushima worse than Chernobyl?
Chernobyl is widely acknowledged to be the worst nuclear accident in history, but a few scientists have argued that the accident at Fukushima was even more destructive. Both events were far worse than the partial meltdown of a nuclear reactor at Three Mile Island near Harrisburg, Pennsylvania.
What is the most radioactive place on earth?
2 Fukushima, Japan Is The Most Radioactive Place On Earth Fukushima is the most radioactive place on Earth. A tsunami led to reactors melting at the Fukushima nuclear power plant. Even though it's been nine years, it doesn't mean the disaster is behind us.
How long will Fukushima be uninhabitable?
100 years A large area around the Fukushima nuclear power plant will be uninhabitable for at least 100 years.
